The invention discloses a city
road traffic crossing in-vehicle traffic information lamp early warning method and
system based on Internet of vehicles. The method is based on the wide application of a
wireless transmitting terminal, and employs a
wireless transmit-receive module for
range finding; a
wireless receiving terminal is provided with a directive antenna so as to limit a reading scope. Meanwhile, based on the installation position of a wireless transmitting terminal,
range finding is more accurate. Comprehensively considering whether a current state is
red light or
green light, and whether vehicles exist in front, the method provides early warning information for current vehicles, allowing the current vehicles to safely and rapidly pass through a crossing. The
system comprises a traffic information collecting and transmitting module, a vehicle wireless transmit-receive module, a self vehicle information collection module, a
lane detection module, a vehicle display module, an acousto-optic alarm module, a power supply module and a
data processing module. A whole
system has a simple structure, is convenient to use, and provides accurate determination and early warning information for vehicle owners based on a provided
algorithm.
